Roselin Morales, 5'9, 160 lbs, 35 years old as of 2006, of Allentown, PA, is the middle child of three, who were all raised in an athletic environment.

Roselin, and her father, and two other siblings all practiced the Martial Arts. By 16 years old, Roselin achieved a yellow belt. She left the Martial Arts in High School to run track and field for Liberty and Freedom High Schools in Bethlehem, PA. At 18 years old she went on to competitive weight lifting, and eventually to body building competition.

Roselin continued her body building and weight lifting until 2000, when she decided to learn how to become a boxer, which was suggested to her by others because of her uncanny ability to throw punches and undoubtedly her intimidating physique.

Roselin boxed in the amateurs from 2000-2003, and turned pro that same year.

On April 26, 2003, in Scranton, PA, Roselin won her pro debut by a four-round majority decision over Darlene Sabo. On July 13, 2003, Allentown, she stopped Connie Bechtel by TKO in the first round. In that same year, on October 23, 2003, in Allentown, she won a four-round split decision over Monica Nunez. In December the following year in Allentown, she TKO Gwen Wood in the first round. In her last fight, in Allentown, she won a six-round unanimous decision over Veronica Rucker.

Other than her boxing career she also is a massage therapist and is an assistant coach for amateur boxers.
